"Last month, online security expert Brian Krebs revealed that an underground identity theft service which illegally sold Social Security numbers had obtained much of its data by conning Experian, one of the three major credit bureaus, into selling it to them. “Secured databases are a much more concentrated target,” says Cormac Herley, a security expert with Microsoft Research. “Thieves are not going after one identity but thousands or millions of them.”
This is simply something we all need to remember and deal with cash-less payments. I would have said "plastic money" but I have been corrected last time I wrote that - the Canadians already have plastic money/cash.... Go Canucks!
